Sound, is the ,vibration, of air particles (compression and expansion) the can reach your ears. But you can have ,vibration, being propagated in liquids and solids as well. Some sounds are generated in structures, so the ,vibration, of a structure is converted to ,sound, in air — for instance, a loudspeaker.
Sound, makes ,vibrations, We are lucky that ,sound, makes ,vibrations,; otherwise, we would have no hearing. ,Sound,, which essentially is just a ,vibration, of the air, makes the little membranes in our ears – the eardrums – vibrate. And these ,vibrations, generate signals that are transmitted to …

Noise is defined as being unwanted ,sound, and is made by pressure variations resulting from ,vibrating, air particles and pressure waves. Sounds and noises can travel through solids and liquids through pressure waves to the human ear.
What is Vibration,? In its simplest form, ,vibration, can be considered to be the oscillation or repetitive motion of an object around an equilibrium position. The equilibrium position is the position the object will attain when the force acting on it is zero. This type of ,vibration, is called "whole body motion", meaning that all parts of the body are moving together in the same direction at any ...
What is vibration,? ,Vibration, is the rapid back-and-forth movement of physical particles, as a reaction to different forces.. ,Vibration, involves the disruption of something from its equilibrium point. This is a balanced state between opposing forces. ,Vibration, is usually discussed in relation to the creation of ,sound,.
Information transmitted by frequency and ,vibration, (energy) passes nearly 100 percent of the information. Lipton added that chemical signals travel through fluids at a speed of about one foot per second; ,vibration,, resonance, and frequency (,sound,) travel at 186,000 miles per second.
The science behind ,sound,. In simple terms, ,sound, is ,vibration,. The complex internal structure of our ears can respond to the waves produced by ,vibration,, whether in the form of bass drum or an acoustic guitar. When an instrument produces ,vibrations,, it creates oscillating ,sound, waves.
A quick definition of ,sound, from Wikipedia: In physics, ,sound, is a ,vibration, that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, ,sound, is the reception of such waves and their perception by the brain.
